大家好，
我正在使用Eigen v.3.3.3，并尝试将Vector3f与浮点数相乘。
Eigen::MatrixXf weighted_adjacency_matrix(2,2); // [n,n]
weighted_adjacency_matrix << 0, 1, 1, 0;
Eigen::Matrix<Eigen::Vector3f, Eigen::Dynamic, 1> locations; // [n]
Eigen::Vector3f vec1(1, 2, 3), vec2(2, 3, 4);
locations << vec1, vec2;
Eigen::Matrix<Eigen::Vector3f, Eigen::Dynamic, Eigen::Dynamic> result = weighted_adjacency_matrix.cwiseProduct(locations);
在代码中，我尝试对两个矩阵进行逐点乘法。
stacktrace如下所示：

为什么不能将Vector3f与浮点数进行逐点乘法运算？
任何解决方案和/或想法将不胜感激！
